I would designate a little more time upfront to LR and RC than I did before diving into practice tests. But in my experience, slow steady work will get you to where you want to be. Stay at it. There will be ups and downs.

Do you have a job where you can do some casual practice problems during slow periods? That helped me from not feeling stressed to cram in 3 hours after work.

If its Thursday, and you've studied 3 hours on Monday, 3 hours on Tuesday, and 3 hours on Wednesday, and you feel yourself losing concentration, just put it away and go watch Real Housewives with your friends. Don't overdo it. At least that's my experience.
